Abstract
In an engine with a cam phase change mechanism which is disposed on one end portion of an intake camshaft and variably changes a phase of a drive cam of an intake valve relative to a crankshaft, the cam phase change mechanism is configured so that two vane-type hydraulic actuators of which variable-phase torques produced at the same supplied oil pressure are different are arranged axially relative to the intake camshaft.
